Abstract
A power stethoscope with integrated speaker includes a compact main body that houses a microphone, a speaker and a sound funnel. The sound funnel has a cap along the bottom end that permits the passage of sound waves for capture by the microphone. A control unit having a processor, a memory and a digital filter is communicatively linked to the microphone and speaker. The memory can record the microphone output, and a communication can transmit the same to an external device.
Description
- This application claims the benefit of U.S. Application Ser. No. 62/174,698 filed on Jun. 12, 2015, the contents of which are incorporated herein by reference.
- The present invention relates generally to medical instruments, and more particularly to an electronic stethoscope having an integrated microphone and speaker.
- The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
- One of the most recognizable medical instruments is the stethoscope, which can be found on or about virtually any medical professional. Although stethoscopes are a staple of the medical community, their design has changed little in more than 100 years. In this regard, conventional stethoscopes utilize a diaphragm that naturally conducts sound through rubber tubing that terminates into binaural earplugs.
- Although these devices work well in the relatively quiet environment of a doctor's office, they are known to be difficult to use in high noise areas such as emergency rooms, trauma centers, and moving vehicles such as ambulances, and/or medical transport aircraft, for example. For these locations, practitioners must utilize specialized medical equipment such as electrocardiographic heart monitors, for example, which utilize a plurality of individual leads that must be accurately positioned on or about the patient's body. Unfortunately, the large size and high cost of such machines means that they are not always available for use when needed by a medical professional.
- Accordingly, it would be beneficial to provide a low cost lightweight power stethoscope with an integrated audio output mechanism that does not suffer from the drawbacks of the above noted devices.
- The present invention is directed to a power stethoscope. One embodiment of the present invention can include a compact main body that houses a microphone, a speaker and a sound funnel. Patient sounds can pass through the funnel to be captured by the microphone and played for a user via the speaker. The stethoscope can also include a control unit having a processor and memory for storing the sound captured by the microphone. This information can be transmitted to other devices via a communication port that is also in communication with the processor.
- In another embodiment, the device can also include a digital audio filter that can process the captured sound to ensure an accurate representation of the same via the speaker, and a power source for providing the necessary power requirements for each device component.
- This summary is provided merely to introduce certain concepts and not to identify key or essential features of the claimed subject matter.
- Presently preferred embodiments are shown in the drawings. It should be appreciated, however, that the invention is not limited to the precise arrangements and instrumentalities shown.
